ABSTRACT:
A hummingbird feeder that rotates to position a feeding hole in close proximity to the level of the liquid contained therein. The feeder, basically circular in cross section, is mounted to allow rotation around the axial center of the circular cross section. One face of the feeder has a hole through which the humming birds drink the liquid. Concentric to the hole is a floatation device which maintains the position of the hole in the close proximity to the surface of the liquid. As the liquid level lowers, the entire assembly rotates to maintain the hole position immediately above the liquid level.
